Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027722, here are decompositions:

5 + 1027717 = 1027722
19 + 1027703 = 1027722
29 + 1027693 = 1027722
43 + 1027679 = 1027722
79 + 1027643 = 1027722
109 + 1027613 = 1027722
131 + 1027591 = 1027722
173 + 1027549 = 1027722

Showing the first eight; more decompositions exist.
